Hmm, it seems i didn't play the movie. Now if i try to change the frame
with a number box or with the message [auto 1(, Pd crash.
I get in the Pd console :
[pix_film:audio_ffmpeg] Codec not found: FFmpeg Sonic decoder
[pix_film]: loaded file: /home/jack/rgba_png.avi with 250 frames
(960x540) at 25.000000 fps
With valgrind, i get :
